Undefined method `per' for #<TeamMember::ActiveRecord_Relation ... and all other dashboard/models [UPDATED/SOLVED]

Hi

I'm trying to access models from the dashboard. I've not needed to do this for a while, but have now come across a problem when trying to access ANY dashboard:

undefined method `per' for #<TeamMember::ActiveRecord_Relation:

Some of the stack trace says:

Application Trace | Framework Trace | Full Traceactiverecord (6.0.0) lib/active_record/relation/delegation.rb:108:in `method_missing'
administrate (c664b5d6f1c8) app/controllers/administrate/application_controller.rb:12:in `index'

activesupport (6.0.0) lib/active_support/callbacks.rb:135:in `run_callbacks'
actionpack (6.0.0) lib/abstract_controller/callbacks.rb:41:in `process_action'

When I look at the administrate/application_controller.rb:12

resources = resources.page(params[:page]).per(records_per_page)

I am unsure if this is something I have done.

Do you have any ideas as to why none of the bashboards will be loading? This includes the ones which set up with jumpstart.

Further to this, I have just checked out and tested previous versions from git and, before I merged the latest jumpstart changes from gitlab it was all working well.

Testing the version after the changes and I am getting the errors shown above.

Does this mean something isn't quite right in the state of Denmark in the administrate gem?

Just trying to help sort the problem!

I have since worked out that installing the simple_discussion gem caused a conflict somewhere (perhaps with will_paginate?) so have deleted the gem and all works. Shame really ... as I really liked the simple_discussion gem  Chris Oliver   (except for the fact it used Bootstrap and not tailwind).

I have just come across the same issue. Is there a way to allow will_paginate to play nicely with kaminari / administrate?

for anyone that comes across this issue, the solution that works for me is https://stackoverflow.com/questions/14958438/rails-activeadmin-undefined-method-per-for-activerecordrelation0x4d15ee#15134941
